Insimbi Engagqwali ye-SS904L AISI 904L (UNS N08904)

Incazelo emfushane:

I-UNS NO8904, eyaziwa kakhulu ngokuthi i-904L, iyinsimbi engagqwali ye-austenitic ene-carbon ephezulu ephansi esetshenziswa kabanzi ezindaweni lapho izakhiwo zokugqwala ze-AISI 316L kanye ne-AISI 317L zinganele. I-904L inikeza ukumelana okuhle kokuqhekeka kokugqwala kokucindezeleka kwe-chloride, ukumelana nomgodi, kanye nokumelana nokugqwala okuvamile okungaphezu kwe-316L kanye ne-317L molybdenum ethuthukisiwe.

Isingeniso Somkhiqizo

Insimbi engagqwali ye-AISI 904L (UNS N08904) iyinsimbi engagqwali ye-austenitic ene-alloy ephezulu. Uma iqhathaniswa ne-316L, i-SS904L inokuqukethwe okuphansi kwekhabhoni (C), okuqukethwe okuphezulu kwe-chromium (Cr), kanye nokuqukethwe okuphindwe kabili kwe-nickel (Ni) kanye ne-molybdenum (Mo)316L, okwenza ibe nokumelana okuphezulu kwe-oxidation ekushiseni okuphezulu, ukumelana nemigodi, kanye nokumelana nokunciphisa i-asidi (isb., i-sulfuric acid). I-nitrogen (N) inganciphisa izinga lokuna kwe-chromium carbide, ngaleyo ndlela inciphise ukuzwela kokuzwela, futhi ithuthukise ukumelana nemigodi kanye nokugqwala okubangelwa ama-chloride. Ikakhulukazi ukungezwa kwayo kwethusi (Cu) kwenza kube wusizo kuzo zonke izingxube ze-sulfuric acid.

I-Alloy 904L isebenza kangcono kunezinye izinsimbi ezingagqwali ze-austenitic ngenxa yokuhlanganiswa okuphezulu kwe-nickel ne-molybdenum. Ibanga alinamagnetic kuzo zonke izimo futhi linokwakheka okuhle kakhulu kanye nokushibilika. Isakhiwo se-austenitic sinikeza leli banga ukuqina okuhle kakhulu, ngisho nasezingeni lokushisa eli-cryogenic. Okuqukethwe okuphezulu kwe-chromium kukhuthaza futhi kugcina ifilimu engasebenzi evikela izinto ezindaweni eziningi ezigqwalisayo. Akukho bungozi bokugqwala kwe-intercrystalline lapho kuphola noma kushibilika ngenxa yokuqukethwe okuphansi kwekhabhoni. Izinga lokushisa layo eliphezulu lenkonzo lingama-450°C. Leli banga liwusizo kakhulu ekusetshenzisweni kwamapayipi okulawula kanye nezinsimbi lapho ama-316 nama-317L engafaneleki.

I-Alloy 904L yasungulwa ekuqaleni ukuze imelane nezimo eziqukethe i-sulfuric acid encibilikisiwe. Iphinde inikeze ukumelana okuhle namanye ama-asidi angaphili njenge-hot phosphoric acid kanye nama-asidi amaningi angaphili.

I-alloy 904L ishintshwa kalula futhi icutshungulwe ngemikhuba ejwayelekile yokwenziwa kwesitolo.

Insimbi engagqwali engu-904L (SS904L) isetshenziswa ku-petroleum, amakhemikhali, umanyolo, imibhoshongo yokuthuthukiswa kolwandle, amathangi, amapayipi namapayipi kanye nemishini yokushintshanisa ukushisa. Abakhiqizi bamawashi i-Rolex nabanye bayayisebenzisa futhi ukwenza amawashi.
